Product Description
Product Description
Curved refractory brick contains Al2O3 about 30% ~ 45%, and silica content is lower than 78%. curved refractory bricks belong to the weak acid refractory materials. curved refractory block is resistant to acid slag and the erosion of acid gases, but the alkali resistance ability is a bit poor. curved refractory blocks have the characters of good thermal performance and good thermal shock resistance.
Properties of Curved Firebrick
- High refractoriness,
- Good corrosion resistance,
- Good thermal shock resistance,
- High mechanical strength,
- High-temperature creep rate is low,
- Good spalling resistance and wear resistance.
